Adding interfaces

[Darren Cook <darrenj@example.com>]

I've been adding a second IP address to my Linux (Debian) test server.
So to /etc/networks/interfaces I duplicated the existing entry, then
changed "eth0" to "eth0:0" and "eth0:1" [1]. I did "ifup -a", and
ssh,ftp, etc. to either address now work, but I've not tried rebooting
yet.

Then I looked at two other machines and saw the first entry was left as
"eth0", and the 2nd address was called "eth0:0", 3rd was "eth0:1". Does
this matter? And should I have changed anything else or is this really
all there is to it?
